by YOKE Templates

This template is free. Launching runs it on a cloud box — $50/mo (2 GB) or $100/mo (4 GB), cancel anytime. You'll pick a size next.
Your swarm runs from the YOKE desktop app: after checkout you install it and sign in to bring the agents online.

Structure

Swarm file (blueprint body)

# stripe-webhook.swarm.toml — a declarative SWARM CONFIG (a GridSnapshot the
# engine boots from via KANE_SNAPSHOT). Infrastructure-as-code for the Stripe
# inbound-webhook control-plane part: it stands up three nodes and wires them.
#
#   [Webhook Trigger] ──hook→verify (Comms payload)──▶ [Script: stripe-verify]
#                                                              ▲
#                                     vault→verify (DataAccess) │  secret as env
#                                                        [Vault]
#
# Node KIND comes from `template_id` (builtin-webhook / -script / -vault).
# Wire KIND is DERIVED from the endpoint kinds at load: vault→script = DataAccess
# (the secret grant), hook→script = Comms (the payload feed).
#
# NOT in this file (provisioned out-of-band, by design): the script's wasm
# module (kane-cli SetScriptModule), the webhook path (UpdateTrigger), and the
# Vault secret (kane-cli secret set). Grid layout is declarative; bytes + secrets
# are not.
